Flat Copper Wire Common Mode Inductor

Common mode inductors are also called common mode chokes. It is often used for EMI filtering of switching power supply to filter electromagnetic interference signals.

Product introduction

Product Introduction

Common mode inductors are also called common mode chokes. It is often used for EMI filtering of switching power supply to filter electromagnetic interference signals. It consists of two coils wound around a ferrite at the same time, the two coils turn the same number. When the interference signal flows through the coil, the two magnetic fields in opposite directions will cancel out. When the common-mode signal passes through, the magnetic flux in the magnetic ring superimposes each other and the coil presents a high impedance characteristic, and a strong damping effect is generated to suppress the common mode current. The final result is to suppress the electromagnetic interference signal generated by the common mode signal.


Products Advantage
    1. Small volume, large current through, the unit current density is more than 1.3 times that of round copper wire;
    2. Low DC resistance, minimal distributed capacitance, efficient heat dissipation;
    3. Closed magnetic circuit, small magnetic leakage, ideal EMC effect, and well conducted radiation effect, and stable consistency.
    4. Adopt fully automatic machine winding, line up neatly, no crossing, high production efficiency; 
    5. simple and convenient, save time, good quality, high efficiency;
    6. High insulation strength, it can extend the lifetime of power supply. 

Application
Flat Copper Wire Common Mode Inductor is applied in many field, mainly for stabilizing current, filtering anti-interference. It’s suitable for switching power supply, CNC industrial power supply, adapter, PC chassis power supply, UPS power supply and other power supplies.
